Elephants have giant, floppy ears because they regulate body temperature in extreme heat. African elephants are the biggest land mammals in the world. African elephants can weigh up to 15,000 pounds.

They are able to pick up a storm’s infrasound, the low frequencies, which are undetectable to the human ear. Unlike most mammals, elephants don’t sweat. They can’t afford the water loss.

Elephants have massive ears to help regulate their body temperature. They have huge blood vessels in their ears. The blood vessels are large and quite visible on the backs of the elephant’s ears.
